The Connection Between Hurricanes and Precipitation in Maryland

Abstract:

Precipitation, though necessary, can affect humanity in disastrous ways. Droughts, floods and other related disasters can costly damage economy. In 2012, Hurricane Sandy, caused a total economic loss of about $65 billion and in the state of Maryland, approximately $13.55 million. The purpose of this study is to determine what, if any effect do hurricanes have on monthly and annual precipitation in Maryland. Furthermore, using this information, discussion can be made on hurricane activity in Maryland and the possible connection to global climate change. To achieve this goal, three objectives were developed to: 1) Gain a better understanding of Maryland’s terrain and how that affects precipitation; 2) Calculate monthly and annual precipitation in the state; and 3) Calculate how much precipitation was contributed by each hurricane. The NASA TRMM Multi-Satellite Precipitation Analysis (TMPA) precipitation products were used. Our results show that hurricanes do significantly affect both monthly and annual precipitation in Maryland, so much so that if removed, most monthly and annual precipitations would be below their averages. The methodology could be applied to other states or regions as well. Giving the global warming scenario, it is important to understand changes of hurricane size, track and intensity since both can have significant impacts on Maryland, which warrants further studies.
